[0002] Alkali leaching is a common method for extracting tellurium, which involves mixing copper telluride or other tellurium-containing materials with an alkaline solution, and converting the tellurium therein into a water-soluble form through a chemical reaction to achieve separation. For example, under the conditions of NaOH concentration, liquid-solid ratio, temperature, etc., the efficient separation of copper telluride and copper telluride can be achieved through a pressurized oxidation alkaline leaching process.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the prior art, the copper telluride leaching process in the precious metal production workshop includes: putting copper telluride particles into the reactor, adding alkali, and turning on the agitator to fully slurry it. During the entire stirring process, the copper telluride particles may not be completely dispersed, resulting in poor slurrying effect, and the sufficiency and stability of the reaction cannot be guaranteed, resulting in low leaching rate, and a large investment in manpower, materials, and time. Using a slurry agitator in this solution can further fully crush the copper telluride, achieve a better slurrying effect, and improve the leaching rate. After experimental analysis, the copper telluride leaching rate using the slurry agitator of this solution was increased from the original 55% to about 60%.

[0029] See also Figure 1 In one embodiment of the utility model application, a slurrying agitator is disclosed, which includes a stirring main rod 10, a plurality of rotating blades 20 and at least one vertical blade 30, wherein a connecting head 11 is provided at the end of the stirring main rod 10, and the connecting head 11 is used for an external driving motor; a plurality of the rotating blades 20 are circumferentially spaced on the outer wall of the stirring main rod 10; the vertical blade 30 is provided on the side of the rotating blade 20 facing the connecting head 11, and a beveled blade edge is provided at the end of the vertical blade 30 away from the rotating blade 20.

[0030] The present embodiment proposes a slurrying agitator, which is provided with a plurality of rotating blades 20. The rotating blades 20 can help improve the mixing uniformity of the materials during the stirring process, ensure that the copper telluride particles are fully dispersed, and prevent agglomeration. At least one vertical blade 30 is provided on the rotating blades 20. The design of the vertical blade 30 can help effectively cut and disperse the copper telluride particles, so that the raw materials are more evenly mixed during the stirring process, thereby improving the slurrying efficiency.

[0031] Specifically, the vertical blade 30 is arranged on the side of the rotating blade 20 facing the connector 11, which can increase the shear force and cutting force of stirring, can better mix the copper telluride raw material with the alkali solution, promote the contact of the reactants and improve the reaction rate. It can also increase the speed of the upward flow, form a strong vortex, make the copper telluride raw material better suspended in the alkali solution, avoid sedimentation and solid accumulation, and improve the leaching effect.

[0032] The combined design of the vertical blade 30 and the rotating blade 20 can speed up the production process, improve production efficiency, and reduce production time and cost.

[0033] like Figure 2 As shown, as another implementation of this embodiment, the end of the rotating blade 20 facing the stirring main rod 10 is at least partially welded to the stirring main rod 10. The welding connection can provide higher strength and rigidity, ensuring that the slurry agitator can withstand greater forces and torques during operation and is not prone to loosening and breaking. The welding connection can eliminate corrosion points that may exist in connection methods such as bolts, improve the corrosion resistance of the slurry agitator, and is suitable for working environments with long-term contact with corrosive media.

[0034] Specifically, the welding method disclosed in this embodiment is to use argon arc welding for continuous welding, and there must be no welding defects such as cracks and pores, and no local overoxidation.

[0035] Specifically, the rotating blade 20 disclosed in this embodiment is tilted on the stirring main rod 10, and the tilt angle between the rotating blade 20 and the horizontal plane is α1, 30°≤α1≤40°. The tilted rotating blade 20 can generate more turbulence and eddy currents during stirring, increase the mixing and convection effect of copper telluride and alkali solution, and help improve the reaction rate of the solute. More effectively push the copper telluride raw material, promote the mixing and slurrying process, and improve the reaction efficiency.

[0036] In a preferred embodiment, the inclination angle α1 is 35°, so as to ensure that the copper telluride particles can be fully dispersed and fully contact with the alkali solution, thereby improving the slurrying effect.

[0037] like Figure 3 As shown, as another implementation of this embodiment, it is disclosed that the end of the vertical blade 30 facing the rotating blade 20 is at least partially welded to the rotating blade 20. The welding connection can tightly connect the components together, reduce the number of connecting parts and the space occupied, and make the entire slurry agitator structure more compact and suitable for equipment with limited space.

[0038] Specifically, the present embodiment discloses that the vertical blade 30 is tiltedly arranged on the rotating blade 20, and the tilt angle between the vertical blade 30 and the rotating blade 20 is α2, 70°≤α2≤90°. By reasonably setting the tilt angle between the vertical blade 30 and the rotating blade 20, the movement trajectory of the material during stirring can be improved, making the mixing more uniform. This helps to ensure that the copper telluride particles can be fully dispersed and fully contacted with the alkali solution, thereby improving the slurrying effect.

[0039] In a preferred embodiment, the inclination angle α2 is 80°, which makes the slurrying process more efficient and reduces the time and energy consumption in the leaching process.

[0040] Specifically, as another implementation of this embodiment, three rotating blades 20 are provided, and the three rotating blades 20 are evenly spaced on the outer wall of the stirring main rod 10. By providing three rotating blades 20 distributed at equal intervals, the vibration of the rotating blades 20 during the stirring process is reduced, and the stability of the equipment is improved. The copper telluride particles can be mixed with the alkali solution more fully, so that they are more evenly dispersed in the solution, thereby improving the slurrying effect. Two vertical blades 30 are provided, and the two vertical blades 30 are evenly spaced and parallel to each other along the length direction of the rotating blade 20. The provision of two vertical blades 30 helps to improve the slurrying effect and the leaching rate, and can improve the efficiency of tellurium extraction, thereby improving the tellurium recovery rate and product purity.

[0041] like Figure 2 and Figure 5 As shown, as another implementation of this embodiment, the diameter of the stirring main rod 10 is Φ, 60 mm ≤ Φ ≤ 80 mm. The larger diameter of the stirring main rod 10 can provide greater stirring force and shear force, making it easier for the copper telluride particles to be fully mixed and slurried with the alkali solution, thereby improving the slurrying effect. The length value of the stirring main rod 10 is l1, 1600 ≤ l1 ≤ 1800. Proper selection of a suitable length of the stirring main rod 10 can make the slurrying agitator more stable and controllable. The longer stirring main rod 10 can effectively reduce the movement resistance of the solution, provide a larger stirring area, and allow the copper telluride particles to better contact with the solution.

[0042] like Figure 4 and Figure 5 As shown, as another implementation of this embodiment, the rotating blade 20 is a fan-shaped rotating blade 20, and the shape and size of the fan-shaped rotating blade 20 can generate stronger stirring power and shear force, so that the copper telluride particles and the alkali solution are better mixed and slurried, and the leaching effect is improved. The width value of the end of the fan-shaped rotating blade 20 close to the stirring main rod 10 is d1, 60 mm≤d1≤80 mm; the width value of the end of the fan-shaped rotating blade 20 away from the stirring main rod 10 is d2, 90 mm≤d2≤110 mm; the design of the fan-shaped rotating blade 20 can force the vortex generated by the solution during the stirring process to diffuse outward, so that the contact between the solution and the copper telluride particles is more sufficient.

[0043] Specifically, the thickness value of the fan-shaped rotating blade 20 is h1, 5 mm ≤ h1 ≤ 15 mm; the length value of the fan-shaped rotating blade 20 is l2, 210 mm ≤ l2 ≤ 230 mm. Appropriate thickness of the fan-shaped rotating blade 20 can increase its rigidity and stability, and improve the wear resistance and service life of the agitator. At the same time, reasonable width and length values ​​can also increase the stability and anti-deformation ability of the rotating blade 20.

[0044] Specifically, as another implementation of this embodiment, the cross-section of the vertical blade 30 is triangular, and the thickness of the vertical blade 30 gradually decreases in the direction away from the rotating blade 20. The free end thereof can well cut the copper telluride raw material, making it easier to disperse in the solution.

[0045] Specifically, the width value of the vertical blade 30 disclosed in this embodiment is d3, 110 mm ≤ d3 ≤ 130 mm; the width value of the vertical blade 30 is greater than the maximum width value of the rotating blade 20, and the width value of the vertical blade 30 is slightly greater than the maximum width value of the rotating blade 20, which can complete more slurrying work in a shorter time, increase the shear and impact forces, and help accelerate the reaction rate between the copper telluride particles and the alkaline solution.

[0046] Specifically, the height value of the vertical blade 30 disclosed in this embodiment is h2, 35 mm≤h2≤45 mm; the length value of the vertical blade 30 is l3, 6 mm≤l3≤10 mm; reasonable width and length values ​​can also make the copper telluride raw material more fully contact with the alkali solution during the stirring process, ensure the uniformity of slurrying, and improve the copper telluride leaching rate.

[0047] Specifically, as another implementation of this embodiment, the end of the vertical blade 30 away from the stirring main rod 10 is in an arc shape. The arc-shaped end can reduce the friction between the rotating blade 20 and the raw material during the stirring process, reduce wear, and extend the service life of the rotating blade 20.

[0048] Specifically, as another implementation of this embodiment, the stirring main rod 10 is a titanium 2 stirring main rod 10; and / or the rotating blade 20 is a titanium 2 rotating blade 20; and / or the vertical blade 30 is a titanium 2 vertical blade 30. Titanium 2 material has excellent corrosion resistance and can resist corrosion from many chemical substances. In the alkali leaching process, titanium 2 material can withstand the corrosion of alkaline solution, ensuring the long-term stable operation of the stirring device.

[0049] It should be noted that the materials of the stirring main rod 10 and the rotating blades 20 are only exemplified in this embodiment, but the protection scope of the present invention is not limited to this. Other types of materials of the stirring main rod 10 and the rotating blades 20 can achieve the technical effects disclosed in this application and should also be within the scope of protection of this application as equivalent replacements for the concept of the present invention.

[0050] Specifically, as another implementation of this embodiment, the bevel blade is a combination of one or more of a flat blade, a full serrated blade, and a half serrated blade. Different types of blade designs can be selected according to specific process requirements and material properties to improve cutting efficiency. A flat blade is suitable for harder materials, a full serrated blade is more suitable for softer materials, and a half serrated blade has advantages in terms of both cutting efficiency and cutting quality.

[0051] In summary, the present application discloses a slurrying agitator, which is provided with a plurality of rotating blades 20. The rotating blades 20 can help improve the mixing uniformity of the materials during the stirring process, ensure that the copper telluride particles are fully dispersed, and prevent agglomeration. At least one vertical blade 30 is provided on the rotating blade 20. The design of the vertical blade 30 can help effectively cut and disperse the copper telluride particles, so that the raw materials are more evenly mixed during the stirring process, thereby improving the slurrying efficiency.

[0052] The vertical blade 30 is arranged on the side of the rotating blade 20 facing the connector 11, which can increase the speed of the upward flow, form a strong vortex, and make the copper telluride raw material better suspended in the alkaline solution, avoid sedimentation and solid accumulation, and improve the leaching effect. The combination design of the vertical blade 30 and the rotating blade 20 can speed up the production process, improve production efficiency, and reduce production time and cost.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0054] It should be noted that the utility model takes a slurry agitator as an example to introduce the specific structure and working principle of the utility model, but the application of the utility model is not limited to the slurry agitator, and can also be applied to the production and use of other similar workpieces.

[0055] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from its scope.
